Not sure is it the right place to ask, but it has bothered me for a while. It seems that eBay is applying sale tax on buyer end pretty randomly. I live in NYC, and when I buy from sellers in CA, I noticed that even for exactly same seller, similar price items, some items will apply a tax automatically on check out, while for others there’s no tax at all (One can check this out buy clicking ‘buy it now’ and directing to the checkout summary page). I called eBay and the customer service person said that Supreme Court passed some new law and that eBay has been collecting sale tax on the buyer end for buyers in NY since June this year, so technically as long as you’re located in NY, you should pay tax on each transaction. Now I’m totally confused, do anybody know what exactly is going on here? Thanks.
